Cold heading is a process that makes use of three techniques: forward extrusion, backward extrusion and upsetting. After cold heading, the work piece undergoes cold working to alter the shape of the metal to near the net shape (almost finished stage) under cold temperatures. Cold heading is also known as cold forming.

Basics of the Cold Heading Process. There are two ways to make a bolt or screw out of a piece of round stock. First, there is screw machining, that cuts excess metal away from a piece of bar stock until what remains is the shape you want. These fasteners start out with a bar stock size equal to the largest diameter of the fastener being made.

Heading is a metalworking process which incorporates the forging, extruding and upsetting process. [dubious – discuss] It is often performed in the cold state, resulting in cold working.This process typically produces a near net shape workpiece, which means the final product is almost finished although it can sometimes create the final product less plating or heat treating.

cold heading and machining. Cold heading and machining both produce high quality, consistent parts. Interestingly, many outside diameter (OD) ground dowels are not actually machined. It is common to pass cold headed blanks through a secondary grinding operation in order to produce the OD ground dowels.
